What type of road surface provides the best friction? a. dirt road b. dry concrete road c. icy road?

b. Dry concrete road

Explanation:

A dry concrete road will provide the best friction. This is because of the smooth surface which helps in better grip and friction. In case of a dirt road the friction will be less because of the loose gravels. Icy road will be very slippery which will reduce the friction. In fact icy road will have least friction out of the three choices.

b

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer
